Anonymisation key

This is used as part of the Pseudonymisation of the data. It is a unique code that means the research team knows your data belongs to just one person, but they don’t have access to any personal details. See also Anonymised / Anonymised data.

Anonymised / Anonymised data

Anonymising something – or making it anonymous – means removing any personal details that could identify the person the data is from, or about. This is often done for research and statistical reasons.

Artificial Intelligence (AI)

Artificial Intelligence (AI) involves using computers to do things that traditionally need human intelligence. For Wysa this means that it uses AI to make the chatbot work and seem more like a human.

Care pathway

Care pathways are a way of planning the journey of a patient, or client, through the service. In this case it is the CNWL IAPT Care pathway that will be followed.

Central North West London NHS Foundation Trust (CNWL)

CNWL is an NHS Foundation Trust that provides healthcare to a third of London’s population, Milton Keynes and Surrey. They run Community Living Well, the IAPT service that the research project is working with.


A chatbot is a text computer program, like when using WhatsApp, that feels like human conversation.

Clinical activity

Consent can be given in person or over the phone (this is called verbal consent), by reading and signing something, or by clicking to say you accept on an app or website.

Consent form

A document you might sign to show you accept, and understand, the research study.

Control group

Information Commissioner’s Office (ICO)

The ICO ensures that, in the UK, the laws regarding keeping and sharing information are followed.

Institute for Cancer Research

The Institute for Cancer Research is one of the research partners for this study. They are involved as the statistician works for them. The statistician works on understanding the data.

Mitigated / mitigation           

When something is put in place to prevent a problem occurring

Patient groups

Group of people with experience of being a patient who have been involved in developing, in this case, the questions being asked as part of the research

Personal data

Personal data is each person’s information about themselves.

Personally Identifiable Information (PII)

Personally identifiable information is information that, when used alone or with other relevant data, can identify an individual.

Primary Research Data

The information collected during this research study.


Where personal information is replaced, or changed, with alternative details. The changed information is then kept separate from your personal details so you can’t be identified.

Referral / Referred

You may be referred to an NHS service, such as IAPT, by your GP or another health professional. You may also self-refer.

Research data          

Research data is any information that has been collected, generated or created as part of the research study. Although usually digital, research data might also include handwritten items such as notebooks and diaries.

Research Ethics Committee

A research ethics committee is a group of people appointed to review research proposals to decide if the research is ethical. This means the research must conform to recognised ethical standards, which includes respecting the dignity, rights, safety, and well-being of the people who take part.

Research Experts

People who have a lot of experience and knowledge of running research studies.

Research partners

Research partners are the different organisations involved in the research project. In this case it is CNWL, Wysa, University of Plymouth and the Institute of Cancer Research who are the research partners.

Risk of physical impact

This refers to any physical problems that could be caused by spending too long using an app on a phone. Such as eye strain or sore hands.

Routine questionnaires

The routine questionnaires in this project are commonly used measures for depression or anxiety. They are known as PHQ9 (Patient Health Questionnaire-9) and GAD7 (General Anxiety Disorder-7).
